the other is used to carry groceries. 

Most dentists chairs go up and down, don't they?
The one I was in went back and forwards.
I thought, "This is unusual."
The dentist said to me,  "Mr. Owens, get out of the filing cabinet."

A man and a woman are sitting next to each other at a bar getting
drunk. The man turns to the woman and asks her why she's so down.
"My husband just left me. He said I'm too kinky in bed," she said.
"What a coincidence! My wife just left me," said the man, "she told
me that I was too kinky for her, too!"
The two talk a little while longer, and finding that they have so
much in common they decide to go back to the woman's house to have
kinky sex.
When they get to the woman's house she turns to the man and says,
"Give me ten minutes, I want to slip into something more comfortable."
She goes into the bathroom and changes into a full leather dominatrix
outfit.
However, as she is coming out of her bathroom, the man is putting on
his coat and walking out the door.
"What happened?" She said, "I thought you wanted to have kinky sex?"
He looks at her and says, "Well, I just screwed your dog and shit in
your purse. I'm done." 

Robinson came home in great excitement and said to his wife, "You'll
never believe it, dear, but I've discovered an entirely new position
for lovemaking."
"Really," said Mrs. Robinson, interested at once. "What is it?"
"Back to back."
"But that's crazy. We can't do anything back to back."
"Yes we can. I've persuaded another couple to help out." 

   It's a beautiful warm spring day and a man and his wife are at the
   zoo. She's wearing a cute, loose-fitting, pink spring dress,
   sleeveless with straps. As they walk through the ape exhibit and pass
   in front of a very large gorilla, the gorilla goes ape.
   
   He jumps up on the bars, holding on with one hand (and 2 feet),
   grunting and pounding his chest with the free hand. He is obviously
   excited at the pretty lady in the wavy dress. The husband, noticing
   the excitement, suggests that his wife tease the poor fellow.
   
   The husband suggests she pucker her lips, wiggle her bottom, and play
   along. She does and Mr. Gorilla gets even more excited, making noises
   that would wake the dead. Then the husband suggests that she let one
   of her straps fall, she does, and Mr. Gorilla is just about to tear
   the bars down. "Now try lifting your dress up your thighs"
   
   ... this drives the gorilla absolutely crazy.
   
   Then, quickly the husband grabs his wife by the hair, rips open the
   door to the cage, slings her in with the gorilla and says, "Now, tell
   HIM you have a headache."
